Abstract
In this paper, we investigate the OFDM-based wireless local area networks (WLANs) operating in the 60 GHz frequency band. The performance of OFDM system is severely degraded by the local oscillator phase noise, which causes both common phase error (CPE) and inter-carrier interference (ICI). We analyze the impact of phase noise on OFDM systems. Moreover, in order to reduce the phase noise problem, we consider the phase noise suppression (PNS) algorithm. Some numerical results are presented to illustrate the effectiveness of the PNS algorithm for OFDM-based 60 GHz WLANs.
